In a related matter, Belt gave conflicting stories to authorities about an infant, saying the child was born in February in a hospital in Siloam Springs, Ark., but taken into protective custody because she failed to have prenatal care.

Arkansas child workers reported they had no record of any birth to Belt in past month, the affidavit states. When confronted with that information, Belt told authorities she had a miscarriage at her residence in August and wrapped the 14-week-old fetus in a T-shirt and buried it about three feet deep in the yard behind the burial sites of the family pets. Belt marked the grave with a white rocks or stones in a triangle shape.

A search of the yard did not turn up any fetal remains, authorities said.
